Best time to visit Goldendale Observatory State Park
Late spring through early fall, roughly May to September, offers the most reliable conditions for RV travel and night-sky viewing, with warm days, dry roads, and the longest program schedules. Summer brings peak programming, including solar viewing and featured night events, but high desert temperatures can climb into the 90s F. Shoulder months like April and October deliver cooler, clearer nights and smaller crowds, though RVers should watch for sudden cold snaps and strong Columbia Gorge winds. Winter visits are possible on clear nights but come with icy roads, limited programming, and freezing temperatures at elevation.

Things to do at Goldendale Observatory State Park
- Nighttime Telescope Viewing Easy
Guided evening programs let visitors look through the park's large public-access 24.5-inch reflector and additional telescopes. Staff astronomers highlight seasonal targets such as planets, star clusters, and galaxies. Programs are scheduled events, so RVers should plan arrival around start times.
- Solar Viewing Programs Easy
Daytime solar viewing uses specialized filtered telescopes to safely observe the sun, including sunspots and prominences. It is a family-friendly option that does not require staying for nighttime programs. Sessions are weather dependent.
- Interpretive Center Exhibits Easy
The renovated interpretive center features exhibits on astronomy, the history of the observatory, and the night sky over the Columbia Plateau. Indoor displays make it a good rainy-day or daytime stop before an evening program. Restrooms and information are available on site.
- Stargazing on the Hilltop Easy
The observatory grounds sit on a hill with broad, dark skies that are ideal for naked-eye and binocular stargazing. The site is recognized for low light pollution and clear high-desert air. Bring warm layers even in summer, as nights cool quickly at elevation.
- Maryhill Museum and Stonehenge Memorial EasyRV parking available
About 25 miles south on the Columbia River, Maryhill Museum of Art and the nearby full-scale Stonehenge replica are popular day trips from Goldendale. Both sites have large parking areas that accommodate RVs. The drive follows scenic stretches of US-97 and SR-14.
- Columbia Hills Historical State Park ModerateRV parking available
Roughly 35 miles southwest, this state park offers hiking, Native American pictograph tours, and Columbia River access. It is a natural pairing with a Goldendale Observatory trip and has campground options for RVs. Pictograph tours require advance reservations.
- Brooks Memorial State Park Hiking ModerateRV parking available
About 13 miles north of Goldendale on US-97, Brooks Memorial offers forested trails and RV-friendly camping on the route to the observatory. It makes a convenient base camp for evening programs. Trails are rated easy to moderate.

How to get to Goldendale Observatory State Park
The park sits on a hill just north of Goldendale, Washington, about a 2 to 2.5 hour drive (roughly 110 miles) east of Portland, Oregon via I-84 and US-97, and about 2.5 hours south of Yakima. RVers should note the steep climb up Columbia Hills and strong crosswinds on US-97 and SR-14 along the Columbia River Gorge, and should plan fuel stops in Goldendale or The Dalles since services thin out quickly. The final approach to the observatory uses narrow local streets with a steep hill, so larger rigs often park lower in town and use a tow vehicle. The nearest major airport for fly-and-rent trips is Portland International Airport (PDX).
